If I read in a chair, Petrush wants to be in my lap. Usually he lies down so that I can rest the Kindle on him. When he insists on sitting up, because he likes to be able to lean back and lick my neck, I have to read over his shoulder. Every once in a while, he will push down the Kindle with his paw and lean in close to the screen, check what I'm reading, give me a dirty look and settle down again.
